I have the same problem, different naming of files in the ldscripts folder broke this. Also, I needed to add a link to a new gcc executable. I don't know how would the plugin find the new gcc otherwise.
Could anyone help me understand how these gcc linkers work? How does gcc map mcu name (from -mmcu= parameter?) to an ldscript file and why are there multiple files with the same name but different extensions? Sorry, I know Java, but not C and especially not GCC internal workings. Here's how my ldscripts directory (from the new msp430 gcc) looks like: http://pastebin.com/TDxeFEha
